Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure for suspending an automobile seat.

(Prior Art) Conventionally, a valley-shaped depression is formed in an automobile seat in order to improve aesthetics or seatability. The recess is formed by suspending the stitched portion of the epidermis on the seat pad along the valley line of the seat pad.

As this suspending structure, a bag-like tension member is sewn to the stitched portion of the epidermis, and the suspending wire is inserted through the tension member,
There is one in which the suspension wire and the insert wire provided on the seat pad are fixed by an ohm clip.

Further, a band-shaped tension member is sewn to the stitched portion of the epidermis, and a hanging edge member made of resin is sewn to the end portion of the tension member, and the hanging edge member and the insert wire of the seat pad are ohm clips. There are things that I decided to fasten.

(Problems to be solved by the invention) However, in the former structure, if the valley line has a U-shape like the seat bottom, U
The hanging wire bent in a letter shape had to be inserted into the bag-shaped pulling member, and the workability was poor.

Further, in the latter structure, as shown in FIG. 8, when the outer skin 11 is sewn, a strip-shaped tension member to which the hanging edge member 12 is sewn is sewn.
13 must be turned along the A direction to follow the seam, but since the hanging edge member 12 is made of resin and has high rigidity, there is a problem that it cannot be turned in the A direction and cannot be sewn. .
Therefore, the tension member 13 and the hanging edge member 12 are 2 in FIG.
As shown by the dotted chain line, it is provided only on the straight line portion and not on the curved line portion, or the former structure is unavoidably adopted.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a suspending structure for an automobile seat, which facilitates sewing and suspending of the outer skin.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a vehicle seat suspension structure in which a sutured portion of the epidermis is suspended along a valley line of the seat pad. A band-shaped first tension member is sewn to the sewn portion that forms a linear stitch, and a resin hanging edge member is sewn to the edge of the tension member to form a curved stitch. A bag-shaped second pulling member is sewn to the sewn portion, and a curved suspending wire matching the seam is inserted into the second pulling member, and the suspending edge member and the suspending wire are attached to the seat pad. It is fixed to an insert wire provided inside.

(Example) Next, the Example of this invention is described according to drawing.

FIG. 1 shows a seat bottom 1 of an automobile seat to which the present invention is applied, and FIGS. 2 to 4 show a seam portion 4 of a skin 3 which matches a U-shaped valley line of a seat pad 2 of the seat. The structure which suspends on the pad 2 is shown.

A portion of the stitched portion 4 of the epidermis 3 that forms a linear stitch
As shown in FIGS. 2 and 3, S ₁ and S ₂ have a strip-shaped first
The portion where the tension member 5 is sewn and forms a curved seam
R ₁ , R ₂ and the straight line portion S ₃ between them are shown in FIGS.
As shown in the figure, the bag-shaped second pulling member 6 is sewn on. These first and second pulling members 5 and 6 are integrally cut as described later. At the edge of the first tension member 5,
The resin-made hanging edge member 7 is sewn to the second pulling member 6
A suspending wire 8 bent in a curved shape that matches the seam is inserted through the inside.

Then, in the straight seam portions S ₁ and S _{2 of} the skin 3,
As shown in the drawing, the hanging edge member 7 is provided with an ohmic clip at appropriate intervals on the insert wire 9 provided in the seat pad 2.
Fastened by 10. Further, in the curved seam portions R ₁ and R _{2 of} the skin 3 and the straight line portion S ₃ between these, as shown in FIG. Ohm clips 10 at appropriate intervals on 9
It is fastened by. As a result, the U-shaped stitched portion 4 of the outer skin 3 is evenly suspended on the seat pad 2 side, and a recess is formed along the valley line portion of the seat pad 2.

As shown in FIG. 5, the outer skin 3 is sewn by first cutting the first tension member 5 and the second tension member 6 integrally, and sewing the hanging edge member 7 to the first tension member 5. I'll do it. Next, when the side skin 3a and the central skin 3b are sewn, as shown in FIG. 6, the integrally cut first and second tension members 5,
Sew 6 at the same time. At this time, the second pulling member 6 is folded back and sewn into a bag shape. The second tension member 2 has a skin 3 as shown by a chain double-dashed line in FIG.
It may be formed into a bag shape in advance before sewing with. Since the second pulling member 6 is flexible, as shown in FIG. 6, when the second pulling member 6 is sewn in a curved shape, the second pulling member 6 can be easily turned in the A direction, so that the sewing operation is easy. .

After the outer skin 3 is sewn in this way, the second tension member 6 is
The suspending wire 8 bent into a curved shape that matches the seam is inserted. Since this suspending wire 8 is short without straight portions on both sides, it can be easily inserted. After inserting the suspending wire 8, the skin 3 is covered on the seat pad 2 with the side skin 3a folded back, and the suspending edge member 7 and the suspending wire 8 are inserted into the insert wire 9 of the seat pad 2. Fasten with ohm clip 10.

In the above embodiment, the sewn portion 4 forming the substantially straight portion S ₃ at the center of the U-shaped stitch, that is, the rear portion of the bag-shaped _second stitch so as to be continuous with the curved portions R ₁ , R 2 Although the tension member 6 is sewn, the first tension member 5 may be sewn to this portion S ₃ like the straight portions S ₁ and S ₂ on both sides.

Further, as shown in FIG. 7, the first tension member 5 which is a separate member.
The second tension member 6 and the second tension member 6 may be sewn together.

(Effects of the Invention) As is apparent from the above description, according to the present invention, since the bag-shaped second tension member is sewn on the curved portion of the seam of the epidermis and it is flexible, the sewing work can be performed easily. It's easy. Further, since the suspending wire is inserted only through the curved second pulling member, the suspending wire is short and can be easily inserted, and the suspending work is easy.
